Description

Technical Field

[0001] This invention relates to the field of truck battery swapping equipment, and more specifically, to a truck-based front compartment obstacle avoidance battery swapping system, method, equipment, and storage medium. Background Technology

[0002] Currently, in side-mounted battery swapping station systems, to ensure a safe distance when the battery swapping robot transports the battery pack, there are generally two arrangements for the battery pack:

[0003] One approach is to have a sufficiently large gap between the battery pack and the truck's front compartment to allow for battery swapping and transport space. However, this battery swapping and transport space usually creates wind resistance, reducing the vehicle's driving energy consumption performance.

[0004] Another type is a truck cab with a movable front compartment. During battery swapping and handling, the front compartment moves to the far end, and after the swapping and handling is completed, it moves to the near end of the battery pack and fits tightly with it. Considering factors such as the stress on the truck equipment, compact structure, and aesthetics, the second type is more common in the market. The movement of the truck cab mainly uses linear motion such as rack and pinion + slider, lead screw + slider, and belt + slider. However, most linearly moving truck cabs require auxiliary structures such as sliding rails. Since the movement trajectory of the cab coincides with the vehicle's travel direction, the truck's inertia directly and continuously affects the displacement of the sliding cab. Furthermore, the truck cab itself is quite heavy. After acceleration or braking, the sliding rails and other structures not only fail to restrain the position of the cab, but if the locking device loosens or falls off, the cab, supported on the sliding rails, can easily slide off the vehicle body, causing serious safety hazards.

[0005] Therefore, the present invention provides a battery swapping system, method, device and storage medium for front compartment avoidance based on trucks. Summary of the Invention

[0006] In view of the problems in the prior art, the purpose of this invention is to provide a front compartment avoidance battery swapping system, method, equipment and storage medium based on trucks. It overcomes the difficulties of the prior art, can realize the front compartment movement to avoid the battery swapping equipment by curvilinear motion, has a compact structure layout, requires little installation space, and greatly improves the safety of the front compartment movement structure.

[0008] A front compartment assembly, located at the front of the truck, on the side of the truck's battery swapping pack facing the front; and

[0009] A set of four-bar linkages is respectively disposed on both sides of the front of the truck. The first link of the four-bar linkage is connected to the front of the truck, and the movable second link, which is opposite to the first link, is connected to the front compartment assembly. Through the synchronous rotation of the third and fourth links of the four-bar linkages, at least part of the front compartment assembly is moved away from the battery swapping pack to expose the battery swapping operation space based on the battery swapping pack, or moved closer to the battery swapping pack to cover the battery swapping operation space.

The third and fourth links are rotatably connected to the first and second links respectively through joint bearings. The first link is integrated into the cab floor of the truck.

[0018] Preferably, each of the four-bar linkages further includes a first nylon limiting member and a second nylon limiting member disposed at both ends of the four-bar linkage, the four-bar linkage, the first nylon limiting member and the second nylon limiting member being located in the same vertical plane, the first nylon limiting member blocking the travel of the third linkage towards the battery swapping pack, and the second nylon limiting member blocking the travel of the fourth linkage towards the front of the truck.

[0023] The four-bar linkage assembly, based on the curved trajectory transmission part, moves the front compartment assembly toward the front of the vehicle, away from the battery swapping pack, to expose the battery swapping operation space;

[0024] The battery swapping equipment enters the battery swapping work space to replace the battery swapping pack;

[0025] The four-link assembly moves the front compartment assembly toward the rear of the vehicle based on the curved trajectory transmission part, approaching the battery swapping pack to block the battery swapping operation space.

[0027] processor;

[0028] A memory in which executable instructions of the processor are stored;

Figure 2 This is a cross-sectional view of the front compartment avoidance battery swapping system based on a truck in the present invention in the driving state. Figure 3 This is a cross-sectional view of the front compartment avoidance battery swapping system based on a truck in the present invention, in the battery swapping state. Figure 4 This is a top view schematic diagram of the truck cab structure of the present invention, which is based on the truck's front compartment obstacle avoidance and battery swapping system. (See diagram below.) Figures 1 to 4 As shown, the truck-mounted front compartment avoidance battery swapping system of the present invention includes: a front compartment assembly and a set of four-bar linkages (i.e., two sets of four-bar linkages). The front compartment assembly is disposed at the front of the truck, located on the side of the battery swapping pack 10 facing the front of the truck. The two sets of four-bar linkages are respectively disposed on both sides of the front of the truck. The first link 8 of the four-bar linkage is connected to the front of the truck, and the movable second link 9, which is opposite to the first link 8, is connected to the front compartment assembly. Through the synchronous rotation of the third link 2 and the fourth link 3 of the four-bar linkage, at least part of the front compartment assembly is moved away from the battery swapping pack 10 based on a curved trajectory to expose the battery swapping operation space 11 based on the battery swapping pack 10, or moved closer to the battery swapping pack 10 to block the battery swapping operation space 11. In this embodiment, the truck can be an unmanned heavy-duty truck based on the battery swapping method, and the entire unmanned cabin or part of the unmanned cabin can be moved by the four-bar linkages of the present invention. Alternatively, the truck in this embodiment could be a traditional truck with a manned cab, with the manned cab moved as a whole by the four-bar linkage assembly of this invention, but this is not a limitation. Based on the shortcomings of track-type front cab movement, this invention provides a structure that achieves front cab movement through curved motion to avoid the battery swapping equipment, thereby avoiding the influence of the truck's inertia on the sliding front cab. Since the front cab's movement trajectory no longer coincides with the vehicle's direction of travel, even if the locking device fails, the front cab can still remain stationary in the horizontal direction, thus improving safety.

[0067] In a preferred embodiment, the front compartment assembly includes a front compartment control box 71 and a front compartment cover 72. The front compartment control box 71 is fixed to the front floor of the truck. A battery swapping work space 11 for the battery swapping equipment 12 to enter is provided between the front compartment control box 71 and the battery swapping pack 10. A four-bar linkage is located on both sides of the front compartment control box 71. The front compartment cover 72 is connected to a second link 9 and moves along the curved trajectory of the second link 9. It has two states: a driving state where it covers the front compartment control box 71 and the battery swapping work space 11, and a battery swapping state where it exposes the battery swapping work space 11 between the front compartment control box 71 and the battery swapping pack 10. The front compartment control box 71 houses various sensors, controllers, or computing units, and is relatively heavy. A battery swapping work space 11 is pre-set between the front compartment control box 71 and the battery swapping pack 10 for the battery swapping equipment 12 to enter and hold the battery swapping pack 10. The front cabin cover 72 is merely a protective cover and is very lightweight. By functionally separating the front cabin control box 71 and the front cabin cover 72, this invention allows the relative movement of the front cabin to be achieved by simply moving the lighter front cabin cover 72 when moving the front cabin. This also reduces the load on the equipment related to moving the front cabin cover 72, enabling the movement of the front cabin to be achieved with only lightweight transmission equipment. This greatly simplifies the structure, reduces costs, and improves reliability, but is not limited to these limitations.

[0068] In a preferred embodiment, the battery swapping pack 10 is a sheet-shaped battery pack arranged perpendicular to the central axis of the truck. The front cover 72 coincides with the outline of the sheet-shaped battery pack based on the projection of the sheet-shaped battery pack along the central axis of the truck. Since the front cover 72 coincides with the outline of the sheet-shaped battery pack, the front cover 72 and the sheet-shaped battery pack are aerodynamically integrated, which further reduces wind resistance, but is not limited thereto.

[0069] In a preferred embodiment, with the front compartment assembly in motion, the four-bar linkage assembly or the front cover 72 is limited by a clamping member (not shown). The clamping member provides a vertically ground-pointing biasing force to the four-bar linkage assembly or the front cover 72. This invention limits the front cover 72 by providing a downward-pressing clamping member, preventing displacement of the front cover 72 along its isomorphic curved trajectory. Furthermore, since the curved trajectory differs from the truck's forward direction of travel, the acceleration or braking forces generated during truck travel have virtually no impact on the clamping member's locking, significantly improving safety. Even in the worst-case scenario, such as when the clamping member fails, the linear acceleration or braking forces cannot drive the front cover 72 to perform curved movement, still essentially maintaining the front cover 72's non-slippage, further enhancing safety, but this is not a limitation.

[0070] In a preferred embodiment, each four-bar linkage assembly further includes a linkage drive assembly 1, one end of which is connected to the cab floor of the truck, and the other end is connected to the third linkage 2 or the fourth linkage 3, but not limited thereto.

[0071] In a preferred embodiment, the linkage drive assembly 1 includes a telescopic rod, one end of which is pivotally connected to the cab floor of the truck, and the other end is hinged to the middle of the third linkage 2 or the fourth linkage 3. The shape of the four-bar linkage assembly can be adjusted by extending and retracting the telescopic rod, but this is not a limitation.

[0072] In a preferred embodiment, the four-bar linkage is a parallelogram structure perpendicular to the ground. During the curved trajectory, the first link 8 and the second link 9 remain parallel. The third link 2 and the fourth link 3 are rotatably connected to the first link 8 and the second link 9 respectively through spherical bearings 4. The first link 8 is integrated into the cab floor of the truck, but is not limited thereto.

[0073] In a preferred embodiment, each four-bar linkage assembly further includes a first nylon limiting member 5 and a second nylon limiting member 6 disposed at both ends of the four-bar linkage assembly, respectively. The four-bar linkage assembly, the first nylon limiting member 5, and the second nylon limiting member 6 are located in the same vertical plane. The first nylon limiting member 5 and the second nylon limiting member 6 each protrude vertically upwards based on the front floor of the truck. The first nylon limiting member 5 blocks the travel of the third link 2 tilting towards the battery swapping pack 10 (limiting the angle at which the third link 2 tilts towards the battery swapping pack 10), and the second nylon limiting member 6 blocks the travel of the fourth link 3 tilting towards the front of the truck (limiting the angle at which the fourth link 3 tilts towards the front of the truck), thereby ensuring that the front cover 72 will not collide with the battery swapping pack 10 or fall in front of the truck, enhancing safety, but not limited thereto.

[0074] Figures 5 to 10 This is a schematic diagram illustrating the battery swapping process of the front compartment obstacle avoidance battery swapping system based on the present invention. (See diagram below.) Figure 5 As shown, the front compartment avoidance battery swapping system based on a truck of the present invention includes: a front compartment assembly and two sets of four-link assemblies. The front compartment assembly is located at the front of the truck, on the side of the battery swapping pack 10 facing the front of the truck. The two sets of four-link assemblies are respectively located on both sides of the front of the truck. The first link 8 of the four-link assembly is connected to the front of the truck, and the movable second link 9, which is opposite to the first link 8, is connected to the front compartment assembly. The front compartment assembly includes a front compartment control box 71 and a front compartment cover 72. The front compartment control box 71 is fixed to the floor of the truck's front. There is a battery swapping operation space 11 between the front compartment control box 71 and the battery swapping pack 10 for the battery swapping equipment 12 to enter. The front compartment cover 72 is connected to the second link 9. The four-link assemblies are located on both sides of the front compartment control box 71. Each set of four-link assemblies also includes a link drive assembly 1 (see...). Figure 1One end of the linkage is connected to the cab floor of the truck, and the other end is connected to the third link 2 or the fourth link 3. The linkage drive assembly 1 includes a telescopic rod, one end of which is pivotally connected to the cab floor of the truck, and the other end is hinged to the middle of the third link 2 or the fourth link 3. The shape of the four-link assembly is adjusted by extending and retracting the telescopic rod. The four-link assembly is a parallelogram structure perpendicular to the ground. During the curved trajectory, the first link 8 and the second link 9 remain parallel, and the third link 2 and the fourth link 3 are respectively connected to the joint bearing 4 (see...). Figure 1 The first link 8 and the second link 9 are rotatably connected, and the first link 8 can be integrated into the cab floor of the truck. Each four-link assembly also includes a first nylon limiting member 5 and a second nylon limiting member 6 disposed at both ends of the four-link assembly. The four-link assembly, the first nylon limiting member 5 and the second nylon limiting member 6 are located in the same vertical plane. The first nylon limiting member 5 blocks the travel of the third link 2 tilting towards the battery pack 10, and the second nylon limiting member 6 blocks the travel of the fourth link 3 tilting towards the cab of the truck. Figure 5 The front compartment cover 72 is in a driving state that covers the front compartment control box 71 and the battery swapping operation space 11, but the front compartment cover 72 does not cover the battery swapping pack 10 to avoid affecting the external heat dissipation of the battery swapping pack 10 (the exposed battery swapping pack 10 is conducive to air heat dissipation). When it arrives at the battery swapping station, the battery swapping truck interacts with the battery swapping equipment 12 (a battery swapping robot with a side-mounted robotic arm) to start the battery swapping process based on front compartment avoidance.

[0075] like Figure 6 , 7 As shown, the third link 2 and the fourth link 3 of the four-bar linkage are driven to rotate synchronously in the clockwise direction by the linkage drive assembly 1. Based on the curved trajectory, the front cabin cover 72 moves away from the battery swapping pack 10 until it is blocked by the second nylon limiter 6, so as to expose the battery swapping operation space 11 based on the battery swapping pack 10. The width of the complete battery swapping operation space 11 is equal to the width S of the preset gap between the front cabin control box 71 and the battery swapping pack 10.

[0076] like Figure 8 As shown, the battery swapping equipment 12 enters the battery swapping operation space 11, grabs the battery swapping pack 10, and delivers it to the battery swapping station. The battery swapping equipment 12 can be a vertical lifting device or a lateral insertion robotic arm, etc., and is not limited to this. Furthermore, the battery swapping equipment 12 retrieves a fully charged battery pack from the battery swapping station and places it back into the pre-set battery compartment position on the truck.

[0077] like Figure 9 , 10As shown, the linkage drive assembly 1 drives the third link 2 and the fourth link 3 of the four-link assembly to rotate synchronously in the counterclockwise direction. Based on the curved trajectory, the front cover 72 approaches the battery swapping pack 10 until it is blocked by the first nylon limiting member 5. The front cover 72 fits against the battery swapping pack 10 to cover the battery swapping operation space 11 based on the battery swapping pack 10. The front cover 72 then covers the front control box 71 and the battery swapping operation space 11 again, and returns to the driving state. At this time, the truck has completed the battery swapping process based on the front cover avoidance and can leave the battery swapping station.

[0078] Figure 11 This is a top view schematic diagram of the truck cab structure of another truck-based battery swapping system for front compartment avoidance, according to the present invention. Figure 11 As shown, in another truck-based front compartment avoidance battery swapping system of the present invention, the front compartment assembly includes: a front compartment control box 71 and a front compartment cover 72. The front compartment control box 71 is fixed to the front of the truck, and a battery swapping working space 11 for the battery swapping equipment 12 to enter is provided between the front compartment control box 71 and the battery swapping pack 10. A four-bar linkage assembly is located on both sides of the front compartment control box 71 and the battery swapping pack 10. The front compartment cover 72 is connected to a second linkage 9. The width and height of the front compartment cover 72 are both greater than the battery swapping pack 10. Following the curved trajectory of the second linkage 9, the front compartment cover 72 has both a driving state where it covers the front compartment control box 71, the battery swapping working space 11, and the battery swapping pack 10, and a battery swapping state where it exposes the battery swapping working space 11 between the front compartment control box 71 and the battery swapping pack 10, but is not limited thereto. Figure 4 The difference in the corresponding structure is that the front cover 72 in this embodiment is larger, completely covering the front control box 71, the battery swapping space 11, and the battery swapping pack 10, making the truck's front end aerodynamically integrated and further reducing wind resistance. Furthermore, since the front cover 72 can cover the battery swapping pack 10, it reduces environmental damage such as rain and wind in harsh weather conditions, enhancing the protection of the battery swapping pack 10, but this is not a limitation. Other technical features are as described above and will not be repeated here.

[0079] Figure 12 This is a flowchart of the front compartment avoidance method for battery-swapping trucks based on the present invention. Figure 12 As shown, the first method for avoiding obstacles in the front compartment of a battery-swapping truck according to the present invention uses the above-mentioned battery-swapping system for avoiding obstacles in the front compartment of a truck for lock installation, and includes the following steps:

[0080] S110, the battery swapping truck and the battery swapping equipment 12 exchange information.

[0081] S120, the four-link assembly moves towards the front of the vehicle based on the curved trajectory transmission section, away from the battery swapping pack 10 to expose the battery swapping work space 11 (see...). Figure 6 , 7 ).

[0082] S130, the battery swapping equipment 12 enters the battery swapping work space 11 to replace the battery swapping pack 10 (see...). Figure 8 ).

[0083] S140, the four-link assembly moves towards the rear of the vehicle based on the curved trajectory transmission section front compartment assembly, approaching the battery swapping pack 10 to obstruct the battery swapping operation space 11. (See...) Figure 9 , 10 The relevant technical features have been described above and will not be repeated here.

[0084] The front compartment avoidance method based on battery swapping truck of the present invention can achieve front compartment movement to avoid battery swapping equipment by means of curved motion. The structure is compact, requires little installation space, and greatly improves the safety of the front compartment movement structure.

[0085] This invention also provides a front compartment avoidance device for battery-swapping trucks, including a processor and a memory storing executable instructions of the processor. The processor is configured to execute steps of a front compartment avoidance method for battery-swapping trucks by executing the executable instructions.

[0086] As shown above, the truck-based front compartment avoidance battery swapping system of this invention in this embodiment can achieve front compartment movement to avoid battery swapping equipment by means of curved motion. It has a compact structure and small installation space requirements, which greatly improves the safety of the front compartment movement structure.

Therefore, various aspects of the present invention can be specifically implemented in the following forms: a completely hardware implementation, a completely software implementation (including firmware, microcode, etc.), or a combination of hardware and software aspects, collectively referred to herein as a "circuit," "module," or "platform."
